Ducati Diavel Service Manual: Changing bulbs
Changing the headlight bulbs
Before replacing a burnt out light bulb, ensure that the replacement bulb has the same voltage and power rating as specified for the lighting device in question (sect. 3 - 1.1, Lights/instrument panel).
Warning
The halogen light bulbs in the headlight become hot when switched on and remain hot for some time after they are switched off. Allow bulbs to cool before replacing them.
The position of the light bulbs in the headlight is as indicated below: low beam (lo), high beam (hi) and parking light (a).
Remove the headlight, as described in the paragraph "renewal of the headlight" of this section.
To access the headlight bulbs loosen the screws (1) and remove the cover (2).

The bulb (4) has a bayonet base: press and twist counter clockwise to remove.
Fit the new bulb (4), insert the tabs on the bulb base into the corresponding slots to ensure the bulb is correctly positioned, push the bulb in and turn clockwise until it clicks into place.
Refit the connector (3) to the lamp (4), the cover (2) to the headlight, then tighten the screws (1).
